Very much along the lines of philobeddoe. I would take some time off, as has been said here, the importance of a clean pipe, free of uncomfortable aftertaste, this makes your taste, desire, be frustrated, making sudden decisions. I have also had similar episodes, but my other self, told me, hey, take some time, and clean the pipes well. Then everything came back to normal, and I still smoke with pleasure. In any case, I wish you all the best.
